Volcanoes Today, 18 Feb 2016: Colima volcano, Popocatépetl, Ambrym

Ambrym (Vanuatu): Wellington VAAC reported an ash plumes from the volcano this morning. Based on satellite observations, an ash cloud rose to 9,000 ft (2,7 km) altitude and drifted east.
This suggests that some explosive activity is occurring at its active vents, at least intermittently, most likely at Marum or Benbow, both of which contain active lava lakes.
Similar reports arrived already earlier this month, but there are no indications of a significant change in activity otherwise.

Colima (Western Mexico): Activity has not changed since the last update. The volcano produces intermittent weak to moderate explosions (every few hours on average) with ash plumes typically rising 500-2000 meters.
Glow at the summit craters is visible most of the time as well.

Popocatépetl (Central Mexico): The volcano’s activity has been comparably low, with less than 10 (and only weak) explosions in the past 7 days combined.
Seismic activity is low, but glow continues to be visible from the crater at night, indicating that very slow extrusion of lava continues.
